@ericwb Great catch! Thanks for submitting a PR with this fix! ✨

I also noticed this reusable could use a product name update. Would you be up for changing the GitHub references in this reusable to our product variable prodname_dotcom? There's an example variable in the first sentence. If not, no worries, we can tack it on from our end. 💖
